For the sequence an = an-1 + an-2 and ai = 2, a2 = 3,

loris [4]

Answer:

$a_1 = 2$

$a_2 = 3$

$a_3 = 5$

$a_4 = 8$

$a_5 = 13$

Step-by-step explanation:

Given

$a_n = a_{n-1} + a_{n-2}$

$a_1 = 2$

$a_2 = 3$

Solving (a): The first term

This has already been given as:

$a_1 = 2$

Solving (b): The second term

This has already been given as:

$a_2 = 3$

Solving (c): The third term

This is calculated as:

$a_n = a_{n-1} + a_{n-2}$

$a_3 = a_{3-1} +a_{3-2}$

$a_3 = a_2 +a_1$

$a_3 = 3 +2$

$a_3 = 5$

Solving (d): The fourth term

This is calculated as:

$a_n = a_{n-1} + a_{n-2}$

$a_4 = a_{4-1} +a_{4-2}$

$a_4 = a_3 +a_2$

$a_4 = 5+3$

$a_4 = 8$

Solving (e): The fifth term

This is calculated as:

$a_n = a_{n-1} + a_{n-2}$

$a_5 = a_{5-1} +a_{5-2}$

$a_5 = a_4 +a_3$

$a_5 = 8+5$

$a_5 = 13$

Find the area of a circle with a diameter of 26 cm. Give your answer in exact form.

ELEN [110]

The area of a circle is calculated as pi*(r^2). Given a diameter of 26 cm, the radius is half the diameter, which is 26/2 = 13 cm.
Therefore the area is pi*(13^2) = 169 pi.

Another alternative formula for the area is pi*(d^2 / 4). Substituting d = 26 would give pi*(26^2 / 4) = pi*(676/4) = 169 pi, which is the same answer.

So the correct answer is C.

How do I solve this? I feel like I'm over thinking everything. thanks.

sesenic [268]

Equation: 26=6(5−4f)

Step 1: Simplify both sides of the equation.

26=6(5−4f)

26=(6)(5)+(6)(−4f)(Distribute)

26=30+−24f

26=−24f+30

Step 2)Flip the equation.

−24f+30=26

Step 3)Subtract 30 from both sides.

−24f+30−30=26−30

−24f=−4

Step 4) Divide both sides by -24.

-24/-24f=-4/-24

f=1/6
